Subject [jira] [Created] (HIVE-6970) HCatInputFormat in hive-hcatalog-core 0.13 does not compatible with hadoop2

Chao Shi created HIVE-6970:
------------------------------

             Summary: HCatInputFormat in hive-hcatalog-core 0.13 does not compatible with
hadoop2
                 Key: HIVE-6970
                 URL: https://issues.apache.org/jira/browse/HIVE-6970
             Project: Hive
          Issue Type: Bug
          Components: HCatalog
    Affects Versions: 0.13.0
            Reporter: Chao Shi


I'm developing HCatalog support for Crunch (CRUNCH-340). Crunch support both hadoop 1 and
2, by specify profile -Phadoop-1 or -Phadoop-2. When I run my program with hadoop2, I got
the following error. I think this was intended to be fixed by HIVE-4460.
